> In Struts 2.2.1 (and also in trunk),
> org.apache.struts2.interceptor.FileUploadInterceptor cleans up uploaded files
> after the action finishes. The first problem is that the action might throw
> an exception. FileUploadInterceptor does not use try...finally, so any
> action exception will result in files not being cleaned up. The second
> problem is that something earlier in the interceptor stack might throw an
> exception, in which case FileUploadInterceptor will not even be invoked. The
> correct solution is for FilterDispatcher to clean up the uploaded files.
